SPECIFICATION forming part of LettersfPatent No. 524,538, dated August14, 1894.

Application filed March 21,1893. Serial No. 467,026. (No model.)

portable heaters, which are more particularly adapted for heating smallrooms, and its object, aside from the fact of its economy ofconstruction, is to enable its heat product to be deflected direct tothe floor, or to draw the colder and damper lower stratas of air in theroom into it, and heat and discharge' them from the top thereof, andthus render the atmosphere dry and Warm, substantially as hereinafterfully described, and as illustrated in the drawings, in Which-- Figure 1is a front elevation of my invention. Fig. 2 is a vertical longitudinalcentral section through the same. Fig. 3 isahorizontal section, taken ondotted line 3, 3, Fig. 2. Fig. 4 is a similar section taken on dottedline 4, 4, Fig. 2. Fig. 5 is a similar section taken on dotted line 5,5, Fig. 2, and Fig. 6 is a detail view showing the compound damper inperspective.

In the drawings A represents the base rim of my improved heater, whichis inclined out- Ward or spreads so as to afford greater stability tothe same, and is provided with a suitable series of perforations a., a,near thejloor. Secured to "this base rim, preferably, so as not tointerfere with the free circulation of air through the perforations a,is a platform B for the lamp C to rest upon, the rear vertical wall ofwhich does not rise above the upper`edges of said rim, and correspondsin curvature to the inner curve of a crescent. The front and rear sidesof the oil receptacle of lamp C are so shaped that it can be easilyplaced in or removed from this platform at will.

The lamp burner and chimney are, preferably, of that common kind thatgenerate considerable heat when the lamp is lighted, and

5o back of them I arrange a deiector b, which extends vertically fromthe top of the oil receptacle of the lamp to the top of the chimneythereof, over which it arches, substantially as shown. ThisI defiector bconstitutes the forward wall of the superstructure of my heater, whichis secured and rises from the basal rim. The rear wall of thissuperstructure, which is secured to said base, is semiscylindrical, andits forward vertical edges are united to the side edges of the defiectorb,thus making a vertical fiue c, which is open at the bottom to the areainclosed by the basal rim and dis'- charges at the top into the hot airchamber D. This hot air chamber is made by completing a cylinder, abovethe plane of the deiector, with what, below the same, constitutes therear wall of the flue c. The hood of the deliector forms the iioor forthe forward half of the chamber D, and its roof is made by a transversepartition d. The cylindrical walls of the chamber D extend a suitabledistance above the partition d, are provided with a series ofperforations e, and are covered by a cover E.

In the hood of the deliector b, next the forward Wall of the chamber D,I make a draft opening f, and in the partition d, next the rear Wall ofthe said chamber, and, preferably, diametrically opposite opening f, Imake a draft opening g. Opening f is open or shut by means of the damperF, the side edges of which come under suitable guideways 7L, h,

and it is moved by means of a longitudinal rod or bar H, which attachesto, and extends from the rear edge of the same. Draft opening g isalways open when opening f is shut, and vice versa. A damper G on theunder side of the partition closes opening g, and itV could be movedindependent of dam perFby a rod or bar I'I extending longitudinally tothe outside of the heater; I prefer, however, to attach the damper G tothe top of a suitable post 7c arising from the bar H, which latter islocated at such a point that when draft opening f is open the saiddamper G closes draft opening g, and when opening f is closed, openinggis open. I

By closing damper F the major part of the radiated heat is deflectedoutward and downward by the deiector. In this event the hood IOC of thedeiector becomes heated to a considerable extent, and thus warms the aircurrents which'enter the heater through the apertures in the basal rim,pass up through the ue c and into chamber D; from whence they passthrough the draft opening g and outv of the perforations in the sides ofthe heater above the partition d.

When draft opening f is open the major part of the products ofcombustion pass into the hot air chamber, in which, as there is nooutlet above, the air becomes thoroughly heated and heats the Walls ofthe heater in the same manner that the sides of a simple cylinder stovebecome heated, and th us produces considerable Warmth.

What I claim as new is- 1. The combination with a lamp, of a basal rimhaving a series of perforations therein, a lamp plat-form, a deiiectorback of said lamp, so constructed that its hood arches over the chimneythereof, and is provided with adraft opening f therein, a iue back ofsaid defiector, and a hot-air chamber above the same which is connectedby said ilue to the area inclosed within said basal rim, and is providedwith a draft opening in its roof, damper Ffor closing opening f, anddamper G for closing the opening in said roof, as set forth.

2. The combination with a lamp, of a basal rim having a series ofperforations therein, a lamp platform, a deflector having a hood whicharches over said lamp and has a draft opening therein, a flue back ofsaid deflector open to the area inclosed by the basal rim, a hot-airchamber above said deiector, to which said iue leads, having a draftopening in its roof, a covered chamber above said hot-air chamber havinga series of perforations, and the dampers F and G, bar I-I and post 7ccon nected to and connecting said dampers so that when said damper Fcloses the draft opening in the hood of the deliector, the draft openingin the roof of the hot-air chamber closes, and vice versa, as set forth.
